3-axis milling and 2-axis turning Post Processors (PP) can be found under this location on your machines ".....\Program Files\Dassault Systemes\B422\win_b64\startup\Manufacturing". To use the right one you prefer, you need to first set your User Preferences on your Machining app. See pic below on how to set them. You can choose either of the 3 PP vendors listed in preferences. Once you are done programming a part, you can select a PP from that specific vendor when you are ready to generate some 'G Codes Output Interactively' (pic below). Please note these are free for 30days (some for 90 days) only when you activate the PP license through 3DEXP. Once that expires, you will need to contact the PP vendor to activate it for a charge. For all 5-axis PP, you have to contact your preferred PP vendor directly. There are sample completed PPR 3dxml files in the aforementioned location that you can import and generate G codes easily.
